The Spectra-Physics Explorer® One™ series combines innovative and leading edge laser technology by uniting control electronics and laser resonator design into the same footprint of its predecessor, the Explorer. Re-engineered to offer the most compact and powerful solution, the Explorer One It’s in the Box™ design sets the pace for innovation and unmatched laser performance in a tiny package.

The Explorer One laser models are available in the UV at 349 nm and 355 nm and now introduced in the green at 532 nm. The Explorer One 349 lasers have a high pulse energy of 60 µJ and 120 µJ at 1 kHz and the new Explorer 532-2Y offers 200 µJ at 10 kHz pulse repetition frequency. The Explorer One 355 has 300 mW average power and the new Explorer One 532-2 provides 2 W of average power at 50 kHz pulse repetition rate.

The Explorer One series’ ease-of-use and handling simplify integration into different tools or instruments. The very small dimensions of the air-cooled Explorer One makes this laser the technology of choice for system integrators who require integrating a UV or green laser into a tight space or small tabletop-like instrument. Only the 24 VDC supply cable and a serial or analog control cable is required to install and operate the laser on a moving system like gantry integration.

Versatility and flexibility is realized by integrating advanced and value-added hardware and software elements such a first pulse suppression, active pulse detection, burst mode, on-demand auto-calibration, and single pulse energy measurements up to 200 kHz. Explorer One’s output power is adjustable to optimize the laser performance to the application needs. Additionally, the system can be operated using TTL and analog control signals. Real-time pulse energy values are available on the integrated analog port. For applications that rely on the synchronization of multiple lasers, the Explorer One offers a dedicated port to operate multiple lasers synchronously or with precisely separated laser pulses.

Based on the proven Explorer architecture, the Explorer One is extremely rugged, highly reliable, and ideal for demanding 24/7 applications. All optical components are soldered in place to ensure exceptional ruggedness and durability in harsh operating environments. No solder flux is used, thereby minimizing organic contaminants that can degrade laser performance. The Explorer One has been tested to endure shock and vibration with accelerations exceeding 100 g\'s.

Explorer One lasers provide superior mode quality (M2 <1.2) over the full repetition range of up to 200 kHz. The Spectra-Physics patented intra-cavity design enables efficient conversion to the green and UV, resulting in the highest pulse-to-pulse stability for consistent processing and higher yields.
